• CFD Analysis of Explosions with Hydrogen-Methane-Air Mixtures in Congested Geometries 

      Lucas, Melodia Perez; Hisken, Helene; Skjold, Trygve; Arntzen, Bjørn Johan (Journal article; Peer reviewed, 2022)
      Hydrogen is an enabler for de-carbonising the energy system in Europe by 2050. In the UK, several projects are investigating the feasibility of gradually blending hydrogen into the natural gas pipelines with the aim to ...
    • Innføring av nytt 1. semester kurs, PTEK100 Introduksjon til Petroleums- og Prosessteknologi 

      Arntzen, Bjørn Johan (UPED-skrift nr. 1/2004, Working paper, 2004)
      Bjørn Arntzen (Det matematisk- naturvitenskapelige fakultet) har ansvaret for et nytt 1.semesterkurs: Introduksjon til Petroleums- og Prosessteknologi, PTEK 100. Han beskriver hensikten med emnet og de valg som måtte taes ...
    • Simplified modelling of explosion propagation by dust lifting in coal mines 

      Skjold, Trygve; Eckhoff, Rolf Kristian; Arntzen, Bjørn Johan; Lebecki, K.; Dyduch, Z.; Klemens, R.; Zydak, P. (Chapter; Peer reviewed, 2007)
      Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of the propagating flame may sustain explosion propagation in coal mine galleries and other industrial facilities. The mechanisms ...
    • Simulating the Influence of Obstacles on Accelerating Dust and Gas Flames 

      Skjold, Trygve; Pu, Y. K.; Arntzen, Bjørn Johan; Hansen, Olav R.; Storvik, Idar E.; Taraldset, Ole Jacob; Eckhoff, Rolf Kristian (Conference lecture, 2005)
    • Visualization of Unsteady Flow in a Multistage Helico-Axial Pump 

      Gundersen, Ted Ørjan Seim; Moënne-Loccoz, Victor; Dupoiron, Marine; Torbergsen, Erik Andre; Balakin, Boris; Arntzen, Bjørn Johan; Hoffmann, Alex Christian (Journal article, 2023)
      Helico-axial pumps are designed to pump mixtures of gas and liquid. Secondary flows and rotor-stator interactions are known to add complexity to the flow field in unshrouded axial-flow turbomachinery. Here we use a high-speed ...
